Specification of Letters Patent.

Patented Dec. 26, 1911.

Application led November 10, 1910. Serial No. 591,687.

To all whom it mm] concern:

Be it known that I, JOSEPH ANRIG, a citi zen of the United States,residing at West Hoboken, in the county of Hudson and State haveinvented certain new and useful Improvements in Tilting Furnace-Grates,of which the following is a This invention relatesto tilting furnacegrates, that may be adj usted to any desired inclined position,depending upon the size of the coal used, and the invention consists ofparts having particular construction and form, and :specially withanother, whereby it is .believed greater convenience and economy 1n thehandling and consumption of fuel results, and the whole is rendered easyto manufacture or to repair. Y

The construction and arrangement comprising this invention isillustrated in the accompanying drawings, of which- Y Figure 1represents a vertical, longitudinal section of a boiler setting andfurnace to which this invention has been applied. Fig. 2 is a horizontalsection through the holding tube or sleevefor the guide rod, and, Eig. 3is a cross-section of the track for the rollers.

Each part illustrated and described is designated throughout the`drawings and specication by the same letter of reference.,

lraising the grate,

Considering the drawings, A represents a boiler B a furnace, int whichcoal enters from a hopper C, descending upon the grate D. The grate hasa front pivot E, and is arranged to be swung upwardly from the positionshown, along the curved back wall F.

The position of the grate illustrated in Fig. 1 is its lowest position,and it may be caused to assume any inclined position up to thehorizontal indicated by the broken. line J3-d. A satisfactory anddurable means for and for holding it secjarely in the position to whichit may be adjusted, comprises the lug G on the grate at the rear,

to which is pivotally'joined a connecting rod the rod andscrew beingalined. To keep the rod and screw in alinement, the breast M of thefurnace has at its lower part the tube m, one end of whichfis threadedto engage v the screw, while the rod enters the other or and its objectis to provide a grate arranged and associated one inner end of thetube.- shown that by operating) the handwheel of the screw, pressure maye exerted upon the rod` K, 'and through connecting rod- H upon It isbelieved to be the rearV of the grate, which willconsel quently be swungupward upon its pivot E. In practice, the breast M of the furnace ismade removable, and carries with'it the hopper, and the grate, andv allthe parts attached thereto. A

In lig` 1 it is shown that the hopper C is attached to and supported bythe 'front orbreast M of the furnace, and the hopper is brought intoplace when thebreast M is moved up to the furnace walls into theposition illustrated.

It will be understood, that when the screw L is turned to raise thegrate, the rollers J take the weight in part, and, it is advantageous toprovide the track y'. for the rollers. The track is best illustrated inFigs. Q-ad 3. 4It will be also noted that the rollers sustain part ofthe weight of the grate and its load of fuel or ashes, when the breast Mis moved outwardly; The breast is moved outwardly, when it is desired todump the grate. Ordinarily, the lire may be adequately manipulated-bymeans of a suitable implement or poker N introduced through the orificen in the furnace'breast. When the grate has. been adjusted to thedesired inclination, and the breast M is in -normal position, the rearof the grate is back wall F to prevent the from falling too fast. dumpthe grate, the breast is moved outwardly as set forth.

Having now described this invention, and explained its mode ofoperation, what claim is 1. In a furnace, 'the cmbination with a furnacehaving a curved back wall, of a fur` nace breast having an opening forthe introduction of fuel, a grate pivotally connected with said breastimmediately below said opening, the rear of the grate being movable up.and down near said curved back wall and upon a like curve whereby fuelis prevented from falling from the rear of the grate, a horizontal screwarranged at thebottom of fuel at the rear If it is desired to nearenough to the curved? sf ioo the breast, a guide rod arranged to bemoved by the screw, means constructed to engage the screw and guide saidrod, a connecting traek constructed and arranged to afford a path forthe rollers whereby the weight of .the grate is supported.

vimmediately below said opening, the rear of the grate being movable upand down near said curved back wall and upon a like curve lwhereby fuelis prevented from falling from the rear of the grate, a horizontal screwar'- 'ranged at the bottom of the breast, a guide rod arranged to bemoved by thescrew,`

means construeted to engage the screw and guide said rod, a connectingrod arranged to pivotally connect said rod and the rear of said grate,rollers arranged at the lower end of the connecting rod, and a trackconstructed and arranged to afford a path for the rollers whereby theWeight of the grate is supported.

lIn testimony whereof l afliX my signature n presence of two witnesses.
